Description:

Plosives are strong blasts of air that create a massive pressure change at the microphone's diaphragm, and happen most often with strong p, t, k, and b sounds.  RX can intelligently remove these from your audio using the De-plosive module.

Sample:

In this voiceover track, we can hear the pronounced p and b sounds.

Steps in RX Audio Editor:

1. Open the audio file in the RX Audio Editor or send it via RX Connect.
2. Select the area where plosives occur and open the De-plosive module.
   
3. Choose one of the presets. For this example we will start with Moderate Reduction.
4. In order to keep the dialogue sounding natural, we want to make sure the most important elements of the voice is preserved when a plosive suddenly occurs. We’ll begin with the following settings:

        Sensitivity = 4.0

        Strength = 6.0

        Frequency limit = 260 Hz

5. Click Preview to listen to the processing before it is applied to your audio.
6. To apply, click Process.

Tips: 

• Make small adjustments. There are just three parameters in the De-plosive module:

       Sensitivity: which determines what will trigger the plosive removal.

       Frequency Limit: which will determine the highest frequency removed by the tool.

       Strength: which will decide how extreme the removal should be.

• Use a windscreen. The simplest solution to plosives is to use a windscreen or pop filter when recording. You can also try setting the microphone slightly off-axis so that the bursts of air don't go directly into the diaphragm.
  
• Switch into Extended Log. Right-click on the Frequency Ruler to adjust the frequency scale to Extended Log so you can easily visualize low frequencies and make precise selections in that area.
• Try Spectral Repair. For stubborn problems, try using the Spectral Repair Replace tool to process just the frequency area where the plosive occurs.
